The first season of the show aired from April 3, 2005 to March 26, 2006. It sees the titular character - My Melody - sent to the human world after being mistaken for an accomplice in the escape of two criminals: Kuromi and Baku. In the human world she meets and begins living with junior high schooler Uta Yumeno, while Kuromi and Baku reach a similar situation with the mysterious and wealthy high schooler Keichi Hiiragi. With the help of Uta, My Melody has to use her magical items to put a stop to Kuromi's mischief and collect 100 pink notes, in order to prevent Kuromi from collecting 100 black notes and unleashing the dark power.

~Kuru Kuru Shuffle~
The second season aired from April 2, 2006 to March 23, 2007. After the defeat of Keichi Hiiragi and the Spirit of the Dark Power, My Melody has to return to her home in Mari Land, while Kuromi and Baku are once again locked in the castle dungeon. However, Kuromi and Baku have no trouble escaping once more and find a second Melody Key, one unrelated to the dark power. Due to this escape, My Melody once again goes to live with Uta Yumeno, now equiped with a new Melody Takt that allows her to perform the spin-around shuffle to summon helpers from Mari Land. Kuromi and Baku return to the Hiiragi Mansion and this time meet Jun Hiiragi, Keichi's younger brother, who has just arrived from London. Due to the events of the previous season, Keichi Hiiragi is sentenced to the tapir punishment, however this is called off due to Kuromi and Baku's escape. Instead, Keichi is given the bunny ears punishment, forcing him to take on the superhero persona Bunny-Eared Mask and assist My Melody when summoned. This time, My Melody and Kuromi continually race to obtain a set of 8 specific notes of each respective colour: Do, Re, Mi, Fa, So, La, Ti and Do. A complete set of notes is no longer the end goal, as instead a complete sets of notes is able to be used to grant a single wish.

The third season aired from April 1, 2007 to March 24, 2008. The episode runtime was cut down from approximately 25 minutes to 10 minutes. Once again following on from the events of the previous season, the King of Mari Land is to be removed from his throne, being held responsible for allowing the Dark Power to cause havoc two years in a row. Things get complicated however, as the last remains of the dark power - in the form of black notes - are unleashed. It is then decided that My Melody will return to the human world to live with Uta Yumeno once more and use her magic items to purify all the black notes she can find. Purifying black notes turns them into twinkle gems and when she has enough to fill her tiara, she will become the ruling princess of Mari Land. Meanwhile, Kuromi is approached by a mysterious woman, who gives Kuromi the dark Melody Key, allowing her to transform Baku and collect anger gems to fill her own tiara, doing so before My Melody completes hers will make Kuromi the dark princess of Mari Land.

Kirara★
The fourth and final season aired from April 6, 2008 to March 29, 2009. While the timeslot is restored to being 25 minutes long, episodes are split into two different segments, rather than single episodes taking the full 25 minute runtime as was the case in previous seasons. The animation style also undergoes a significant change of direction. This season does not follow on from the others chronologically, instead being set sometime before the events of the first. After being invited to visit by the King, a young girl named Kirara Hoshizuki arrives in Mari Land hoping to see the monthly shooting star. Unfortunately - due to the King and Baku being launched into it - the shooting star crashes into the gateway between Mari Land and the Human world, destroying it in the process and leaving Kirara stuck in Mari Land. Further still, Prince Sorara of the Wishing-Star Land crash lands and turns into a chicken thanks to Baku's wish for cool guys to disappear. With both Kirara and Sorara unable to return home, My Melody, Kuromi and Baku set out on a journey with their new friends to recover the fragments of the wishing star that was destroyed, in order to restore Sorara's true form and return Kirara home.
